How do you keep pressing on when you get stomped real hard?

The last game I played I got stomped so hard that I was supremely depressed and couldn't bring myself to play another game. I just sat there all feeling like total garbage and the next thing I knew I was closing the client.

This isn't a one time thing either, this happens to me all the time. I don't want to call it salt but I just felt so tilted that I felt like I hated the world and that I should have done better. Carried my team somehow. But I just sucked as much as everyone else and kept getting caught out trying to make plays in our favour.

The enemy Taric was a God. He turned so many fights by just doing everything perfectly to save his team. Enemy LeBlanc got fed on our Teemo like it was Thanksgiving dinner or something. The enemy teams map presence and rotation was flawless and made my team look like babies playing chess. These kind of games drive me insane and I just want to put my fist through a wall. What makes this all worse is i got caught level 1 in the river and gave first blood +3 assists. It immediately put the enemy team ahead.

Does anyone else have games like these? Can you relate to my feelings? How do you cheer yourself up and put yourself in the mood for more league? How do you push past the fear of having another game like that and exploding like a thermo-nuke? (on the inside, i don't really vent my rage in any way. I just shove it down and do something else)

Eventually I forget the fear and queue up again days later. And then it happens again...

I want to end this by saying that I'm never toxic in my games if that's what you're thinking happens. I'm not really a toxic person.

#TLDR; League drives me into a depressive state when I get stomped and I feel like exploding, but can't because I am a rather big dude and could potentially destroy things around me that I like a lot. How do you conquer the fear of these stomps?

Edit for spelling.
